Update on the balloon/flag issue
I ran a test run on Edmund Scientific Weather ballons this week. Sad to say they worked well, sort of.
I used 8 foot ballons, blew them up to about 4 feet (So they would last longer) had to refill them every 12 hours and they popped in about a day and a half. Thus I'd call the expierment a failure
So much for the low cost idea, would work for Field day if I used a larger ballong and again, blew it up half way, but not for 2 weeks
Next I'm going to investigate advertising ballons. So far Google has NOT been my friend. I do expect these to cost more than I'm really comfortable with, but if they work as well as I hope... I'll spring for one. (Will advise) if anyone knows a company that makes them, Please, Let me know.
I still need a copy of the vector graphics file or other "larger than what' son the forum home page" graphic
Oh yes, since I'm using the balloons to hold up one end of a long wire antenna... That worked well for receive, did not talk to anyone with it, however I got my mobile antenna "tower" up (A 20 foot Sunsetter Flagpole, at least I think it's a 20, 2 sections higher than the 12 foot roof) Antennas on this include a 70cm "T" pole (Look up J pole, that is the desigh chart only use radiators off BOTH sides of the "J") a 2Mtr "T" pole and a 6Mtr Dipole. I was listening to 52.525 MHZ with the rig and heard a voice come in very clear, Turns out Dave was about 75miles S.W. of Washington DC. I'm about 20 miles East of West Branch Michigan (Saginaw bay area, Travers City is further east from where I was) Not bad for 6Mtr FM, 100 watts on my end, don't yet know what he was running
